FIELD OF THE INVENTION

The field of the invention relates to seat back systems for passengerseats or the like.

BACKGROUND

Many passenger seats such as those on passenger aircraft, buses, trains,and the like are arranged so that each passenger seat, other than theforward-most located passenger seats, faces the back of the next forwardpassenger seat. To increase a passenger's comfort and enjoyment, manypassenger seat backs are utilized to install amenities for thepassenger's use during the trip. For example, an upper surface of theseat back may be used to install In-Flight Entertainment (“IFE”)equipment or as an area for additional storage of amenities, such asreading materials or other devices.

In some instances, a tray table may be mounted adjacent a lower surfaceof the seat back. The tray table is deployed by the passenger to providea relatively flat surface for eating, working, recreation, or otheruses.

Conventionally, these amenities and/or tray tables have been mounted toan exterior surface of the seat back, which often encroaches on thespace available to the aft-seated passenger. In certain situations, itmay be desirable to reduce the passenger space occupied by the amenitiesand/or by the tray table when the tray table is stowed. It may also bedesirable to provide a way for the tray table to pivotally couple to theseat back in a conventional location, while minimizing the spacerequired to stow the table body.

SUMMARY

Embodiments of the present invention include a seat back assemblycomprising a seat back with a recess and a tray table assemblycomprising a table body and at least one arm. In one embodiment, thetable body is configured to substantially fit within the recess and ispivotally coupled to the at least one arm. The at least one arm is thenpivotally coupled at a second end to a pivot shaft exterior of alocation where the seat back is pivotally coupled to the pivot shaft. Inother embodiments, an amenity compartment is coupled to the seat backabove the tray table assembly and may be configured to alsosubstantially fit within the recess.

DETAILED DESCRIPTION

Embodiments of the invention provide seat back assemblies for use with apassenger seat. While the seat back assemblies are discussed for usewith aircraft seats, they are by no means so limited. Rather,embodiments of the seat back assemblies may be used in passenger seatsor other seats of any type or otherwise as desired.

FIGS. 1-3 and 5-26 illustrate embodiments of a seat back assembly 10.The seat back assembly 10 comprises a seat back 12, an amenitycompartment 14, and a tray table assembly 16.

The seat back 12 comprises a recess 18 that may be formed by a backsurface 20 surrounded on at least three sides by a lip 22. The backsurface 20 and the lip 22 may be formed of materials including but notlimited to aluminum, stainless steel, other metallic materials,composite materials, or other similar materials. In these embodiments,such as the embodiments illustrated in FIGS. 1-2, 8-9, 11-12, 15-19, therecess 18 may have any suitable shape including but not limited torectilinear, trapezoidal, parabolic, or other suitable shape that doesnot exceed the outer perimeter of the seat back 12. In addition, therecess 18 may have any suitable depth that does not exceed the overallthickness of the seat back 12. In some embodiments, the depth of therecess 18 may have approximately the same dimension as the thickness ofthe seat back 12. In other embodiments, the depth of the recess 18 maybe less than the thickness of the seat back 12.

In some embodiments, the amenity compartment 14 is coupled to an uppersection 24 of the recess 18, and the tray table assembly 16 is coupledto a lower section 26 of the recess 18. The amenity compartment 14 maybe any suitable compartment including but not limited to an enclosuredevice for mounting a display or other entertainment device (also knownas a bezel), an upper literature pocket, or a multi-port compartment tostore additional passenger amenities. In the embodiments illustrated inFIGS. 1-3, 5-10, 17A-C, 19-26, the amenity compartment 14 is a bezel. Inthe embodiments illustrated in FIGS. 11-16 and 18A-C, the amenitycompartment 14 is an upper literature pocket. However, one of skill inthe relevant art will understand that any suitable compartment or devicemay be coupled to the upper section 24 of the recess 18.

The amenity compartment 14 is configured to substantially stow withinthe upper section 24 of the recess 18. The amenity compartment 14 may beformed of materials including but not limited to injection molded orthermoformed plastic, aluminum, sheet metal, stainless steel, othermetallic materials, composite materials, or other similar materials. Inthese embodiments, the amenity compartment 14 is shaped to substantiallyconform to the shape of the upper section 24. In other embodiments, theamenity compartment 14 may have a shape that differs from the shape ofthe upper section 24, while still fitting within the shape of the uppersection 24. For example, the upper section 24 may have a rectilinearshape, while the amenity compartment 14 may have a trapezoidal shapethat fits within the rectilinear shape of the upper section 24. As aresult, the amenity compartment 14 may have any suitable shape includingbut not limited to rectilinear, trapezoidal, parabolic, or othersuitable shape that fits within the shape of the upper section 24.

Because the amenity compartment 14 is configured to substantially fitwithin the upper section 24 to minimize the amount of intrusion into theaft-seated passenger's space, the amenity compartment 14 may have anysuitable thickness that approximates the depth of the upper section 24.In some embodiments, such as the embodiments illustrated in FIGS. 1-3and 5-26, the pocket 14 may have any appropriate depth that allows anouter surface 28 to align substantially flush with an outer edge of theupper section 24. In other embodiments, it may be sufficient for aportion of the amenity compartment 14 to be surrounded by the uppersection 24, while another portion of the amenity compartment 14 extendsinto the space outside the upper section 24.

In some embodiments, such as the embodiments illustrated in FIGS. 17A-19and 22-26, the back surface 20 of the upper section 24 includes at leastone slotted bracket 30 and at least one mounting bracket 32. The amenitycompartment 14 includes at least one hook 34 that is configured toengage the slotted bracket 30. An inner surface 36 of the amenitycompartment 14 also includes at least one projection 38. The at leastone projection 38 is configured to engage at least one receptacle 40located on the back surface 20. In some embodiments, the at least oneprojection 38 is a plurality of ball detents, and the at least onereceptacle 40 is a plurality of ball receptacles. The receptacle 40 maybe positioned on the mounting bracket 32 or may be positioned in otherlocations on the back surface 20. One of skill in the relevant art willunderstand that any suitable number and location of projections 38 andreceptacles 40 may be used to secure the amenity compartment 14 to theback surface 20.

To couple the amenity compartment 14 to the seat back 12, an upper end42 of the amenity compartment 14 is tilted into the seat back 12 so thatthe hook 34 is inserted into the slotted bracket 30. The amenitycompartment 14 is then rotated so that an inner surface 36 of theamenity compartment 14 is adjacent the mounting bracket 32 and the atleast one projection 38 engages with the at least one receptacle 40. Inthe embodiments illustrated in FIGS. 17A-C, 19, and 22-26, the mountingbracket 32 is configured to couple with the inner surface 36 of thebezel 14. In other embodiments, the mounting bracket 32 may have anysuitable shape or configuration that allows the mounting bracket 32 tocouple with the inner surface 36 of the amenity compartment 14 based onthe particular configuration and/or type of amenity to be housed withinthe amenity compartment 14.

The hook/slotted bracket coupling and the projection/receptacle couplingallow the amenity compartment 14 to snap into place on the seat back 12.One of skill in the relevant art will understand that other suitablesnap-fit designs or other suitable mechanical fasteners may be used tocouple the amenity compartment 14 to the seat back 12. The method ofassembly allows for easy installation and removal of the amenitycompartment 14.

The amenity compartment 14 may also be secured to the mounting bracket32 via mechanical fasteners 108 that are inserted through a lowersurface 44 of the amenity compartment 14. The mechanical fasteners 108ensure that tools are needed to remove the amenity compartment 14 toprevent tampering during flight and provide additional security for theamenity compartment 14.

FIGS. 17A-18C illustrate methods of coupling the amenity compartment 14to the back surface 20 and demonstrate that the method is the samewhether the amenity compartment 14 is a bezel (FIGS. 17A-17C) or apocket (FIGS. 18A-18C). The method is also the same for otherembodiments of the amenity compartment 14.

In some embodiments, a shroud 46 may be installed between the amenitycompartment 14 and the seat back 12. The shroud 46 is typically formedof a material that resists stains and is easily and quickly sanitizedbetween passenger uses. Suitable materials for forming the shroudinclude but are not limited to plastics (vacuformed, injection molded,or thermoformed), such as polycarbonate, polyethylene, polypropylene,polyvinyl chloride, or other similar plastics, metallic materials,composite materials, or other similar materials. As a result, the shroud46 provides a protective covering for at least a portion of the seatback 12.

In these embodiments, the shroud 46 is coupled to at least a portion ofthe seat back 12. The shroud 46 is shaped to substantially conform to atleast an outer perimeter of the upper section 24 and an aft surface 48of the lip 22 (partial shroud embodiment). The shroud 46 may optionallyextend downward to also substantially conform to the back surface 20 ofa lower section 26 of the recess 18 and the aft surface 48 of the lip 22(full shroud embodiment). Any portions of the back surface 20 notcovered by the shroud 46 are typically enclosed with a dress cover 52.

The portion of the shroud 46 located in the upper section 24 is shapedto cover the outer perimeter shape of the upper section 24, but mayinclude an aperture 50 in the region behind the amenity compartment 14.The shroud 46 material is not included behind the amenity compartment 14because it does not provide additional aesthetic or protective benefitand adds unnecessary weight to the shroud 46. The aperture 50 alsoprovides an area through which the slotted bracket 30 and the mountingbracket 32 may extend to couple with the amenity compartment 14. Theshroud 46 is pulled snugly against the back surface 20 by the couplingof the amenity compartment 14 to the upper section 24 without the needfor additional fasteners. In the full shroud embodiment, as illustratedin FIGS. 1-3, 15, and 22, additional fasteners 74 may be used to securethe shroud 46 to the lower section 26 of the recess 18.

In the embodiments illustrated in FIGS. 1-3, 8, 17A-C, and 19, theshroud 46 is configured to couple between the seat back 12 and the bezel14. In other embodiments, the shroud 46 may have any suitable shape orconfiguration that allows the shroud 46 to couple between the seat back12 and the amenity compartment 14 based on the particular configurationand/or type of amenity to be housed within the amenity compartment 14.

In other embodiments, the dress cover 52 may be installed between theamenity compartment 14 and the seat back 12 using the same amenitycompartment 14 design that is used when the shroud 46 is positionedbetween the amenity compartment 14 and the seat back 12. The dress cover52 may be formed of materials including but not limited to leather,fabric, or other similar upholstery materials. The dress cover 52 isshaped to cover substantially all of the back surface 20. The dresscover 52 is pulled snugly against the back surface 20 by the coupling ofthe amenity compartment 14 to the upper section 24 without the need foradditional fasteners. In some embodiments, the dress cover 52 and backsurface 20 may include hook and loop type fasteners to further securethe dress cover 52 to the back surface 20. The dress cover 52 may alsoinclude apertures (not shown) through which the slotted bracket 30 andthe mounting bracket 32 may extend to couple with the amenitycompartment 14.

In the embodiments where the amenity compartment 14 is a bezel, such asthe embodiments illustrated in FIGS. 1-2, 8-9, and 17A-C, the bezel 14is configured to form an enclosure 54 between the back surface 20 andthe outer surface 28. The enclosure 54 is shaped to secure a display foran IFE or other entertainment devices, including but not limited todisplays manufactured by Panasonic, Thales, or other manufacturers. Theouter surface 28 also includes an aperture 56 to ensure that the displayis visible when positioned within the enclosure 54. In some embodiments,the outer surface 28 is angled so that the display is tilted upward forbetter viewing by a passenger seated in the passenger located aft of theseat back 12.

The bezel 14 may include slots 58 in the lower surface 44 for passivecooling of the IFE display. To improve cooling of the IFE display, thebezel 14 is often used in combination with the shroud 46. FIG. 8illustrates the use of the bezel 14 in combination with the partialshroud 46 embodiment. FIGS. 1-3 illustrate the use of the bezel 14 incombination with the full shroud 46 embodiment. In some instances,depending on the type of device being secured and the amount of heatgenerated by that device, the bezel 14 may also be used in combinationwith the dress cover 52 only, as illustrated in FIG. 9.

In the embodiments where the amenity compartment 14 is an upperliterature pocket, such as the embodiments illustrated in FIGS. 11-16and 18A-C, the pocket 14 is configured so that the entire pocket 14 islocated above the tray table assembly 16. In these embodiments, thepocket 14 is shaped to hold literature in a sideways or “landscape”orientation. The sideways orientation of the pocket 14 allows the pocket14 to have a shorter length, which in turn provides additional space tomaximize the length of the tray table assembly 16 without an edge 82 ofthe tray table assembly 16 overlapping a lower end 60 of the pocket 14.In some embodiments, such as the embodiment illustrated in FIG. 14, thelower end 60 of the pocket 14 is formed by a plurality of slots 62. Theslots 62 allow dirt and debris inside the pocket 14 to fall to thefloor, thus preventing particle entrapment within the pocket 14.

FIGS. 11-12 illustrate the use of the pocket 14 in combination with thedress cover 52 only. FIG. 15 illustrates the use of the pocket 14 incombination with the full shroud 46 embodiment. FIG. 16 illustrates theuse of the pocket 14 in combination with the partial shroud 46embodiment.

In some embodiments, the tray table assembly 16 is coupled to the seatback 12 below the amenity compartment 14. The tray table assembly 16comprises a pair of arms 64 and a table body 66. The internal structureof the table body 66 may be formed of materials including but notlimited to aluminum, stainless steel, aramid fibers, polycarbonate,polypropylene, other metallic materials, composite materials, or othersimilar materials. In some embodiments, the internal structure of thetable body 66 has a honeycomb structure, where the honeycomb structurecomprises an arrangement of hollow tubes that are coupled to one anotheralong the length of the hollow tubes. The hollow tubes may have acylindrical, hexagonal, or other similar cross-sectional shape. Use ofthe honeycomb internal structure provides the necessary structuralintegrity for the table body 66 while minimizing the weight of the tablebody 66.

In other embodiments, the internal structure of the table body 66comprises a frame that forms the outline of the table body 66, where theframe provides the necessary structural integrity of the table body 66while minimizing the weight of the table body 66. In this embodiment,the internal structure of the table body 66 may also include at leastone bar that connects two sides of the frame to provide additionalstructural integrity to the table body 66. The number of bars that areused is dependent on, among other factors, the size of the table body66, the type of material used to form the frame, and the amount ofstructural integrity required for the table body 66.

The internal structure of the table body 66 may be enclosed by a cover68. In some embodiments, the internal structure of the table body 66 andthe cover 68 may be integrally formed. The cover 68 may be formed ofmaterials including but not limited to polycarbonate, polypropylene,other plastic materials, metallic materials, composite materials, orother similar materials. One of skill in the art will understand thatany suitable cover and internal structure may be used to form the tablebody 66 that will provide a lightweight, slim table body 66 havingsufficient strength to withstand forces that may be placed on the traytable assembly 16.

In some embodiments, such as the embodiments illustrated in FIGS. 2-3,5, 8-9, 11-13, and 15-16, the table body 66 is configured to stow withinthe lower section 26 of the recess 18. In these embodiments, the tablebody 66 is shaped to substantially conform to the shape of the lowersection 26. In other embodiments, the table body 66 may have a shapethat differs from the shape of the lower section 26, while still fittingwithin the shape of the lower section 26. For example, the lower section26 may have a rectilinear shape, while the table body 66 may have atrapezoidal shape that fits within the rectilinear shape of the lowersection 26. As a result, the table body 66 may have any suitable shapeincluding but not limited to rectilinear, trapezoidal, parabolic, orother suitable shape that fits within the shape of the lower section 26.

Likewise, because the table body 66 is configured to substantially fitwithin the lower section 26 to minimize the space occupied by the traytable assembly 16 when stowed, the table body 66 may have any suitablethickness that approximates the depth of the lower section 26. Forexample, in the embodiments illustrated in FIGS. 2-3, 5, 8-9, 11-13, and15-16, the thickness of the table body 66 may be any appropriatethickness that will allow the table body 66 to stow flush with an outeredge of the lower section 26. In this embodiment, the thickness of thetable body 66 is less than one inch, and preferably not greater thanone-half inch. In other embodiments, it may be sufficient to partiallystow the table body 66 within lower section 26, such that a portion ofthe table body 66 is partially surrounded by the lower section 26, whileanother portion of the table body 66 extends into the space outside thelower section 26.

The appropriate size of the lower section 26 and the thickness of thetable body 66 for the various embodiments is dependent on, among otherfactors, the amount of cushioning desired for the seat back 12, theamount of space desired for the passenger, the size and material of thetable body 66, and the amount of structural integrity required for thetable body 66.

In some embodiments, such as the embodiments illustrated in FIGS. 2-3,5, 8-9, 11-12, and 15-16, the table body 66 is pivotally coupled to afirst end of each arm 64 located at each side of the table body 66. Inother embodiments, the table body 66 may be pivotally coupled to asingle arm 64 located in the center or to one side of the table body 66.In yet other embodiments, the table body 66 may be coupled to three ormore arms 64.

The arms 64 may be formed of materials including but not limited toaluminum, stainless steel, polycarbonate, polypropylene, other metallicmaterials, composite materials, or other similar materials. In someembodiments, such as the embodiments illustrated in FIGS. 2-3, 5, 8-9,11-12, and 15-16, each arm 64 is positioned on an exterior side of theseat back 12. Each arm 64 comprises a second end that is configured topivotally couple to a pivot shaft 70 that is also pivotally coupled tothe seat back 12. In some embodiments, each arm 64 is pivotally coupledto the pivot shaft 70 exterior of the location where the seat back 12 ispivotally coupled to the pivot shaft 70. In these embodiments, anextension 72 is used to couple each arm 64 to the table body 66 when thetable body 66 is configured to stow substantially within the lowersection 26. One of skill in the relevant art will understand that anysuitable materials and shapes may be used to form the arms 64 that allowthe table body 66 to stow substantially within the lower section 26, thearms 64 to be positioned on the exterior sides of the seat back 12, andthat provide sufficient strength to withstand forces that may be placedon the tray table assembly 16.

In the embodiments illustrated in FIGS. 1-3, 7-9, 11-16, 20-22, alatching mechanism 76 may be used to releasably engage the tray tableassembly 16 with the amenity compartment 14 to maintain the tray tableassembly 16 in a stowed position. To engage the latching mechanism 76,the table body 66 includes a latch keeper 78. The latch keeper 78 iscoupled to a recess 80 that is located along the edge 82 of the tablebody 66. The recess 80 may be formed of materials including but notlimited to plastics, foam, metallic materials, composite materials, orother similar materials. In some embodiments, the recess 80 may beintegrally formed with the table body 66. In other embodiments, therecess 80 may be inserted into the table body 66. The recess 80 may haveany suitable configuration that secures the latch keeper 78 within thetable body 66. In some embodiments, the latch keeper 78 is coupled tothe recess 80 via mechanical fasteners. However, one of skill in therelevant art will understand that any suitable mechanical or chemicalfasteners may be used to couple the latch keeper 78 to the recess 80and, in turn, to secure the recess 80 to the table body 66.

The latch keeper 78 includes a receptacle 84 that is configured toreceive a projection 86 from the latching mechanism 76 to maintain thetray table assembly 16 in a stowed position. The latch keeper 78 may beformed of materials including but not limited to aluminum, sheet metal,stainless steel, other metallic materials, composite materials, plasticmaterials, or other similar materials.

In some embodiments, the latching mechanism 76 is positioned adjacentthe lower surface 44 of the amenity compartment 14. The latchingmechanism 76 includes a lever 90, which is configured so that an end 92of the lever 90 extends through an aperture 94 in the outer surface 28.The lever 90 may be formed of materials including but not limited toplastics, metallic materials, composite materials, or other similarmaterials.

The lever 90 also comprises extensions 96 that are pivotally coupled toa bracket 98. In the embodiments illustrated in FIGS. 7 and 20-21, thebracket 98 is configured to couple to the bezel 14. In otherembodiments, the bracket 98 may have any suitable shape or configurationthat allows the bracket 98 to couple with the amenity compartment 14based on the particular configuration and/or type of amenity to behoused within the amenity compartment 14.

A compressing device 100 is coupled to the lever 90 and the bracket 98,so that the compressing device 100 applies a force to the lever 90 tohold the latching mechanism 76 in the engaged position so that the end92 is positioned adjacent a lower edge 102 of the aperture 94. In someembodiments, the compressing device 100 may be a torsion spring.However, one of skill in the relevant art will understand that anysuitable device may be used to apply a suitable force that maintains thelatching mechanism 76 in the engaged position.

A passenger may apply an external force to the lever 90 to overcome theforce applied by the compressing device 100 by lifting the lever 90,which transitions the latching mechanism 76 from the engaged position tothe disengaged position. When the latching mechanism 76 is held in thedisengaged position by the passenger, the end 92 is positioned adjacentan upper edge 104 of the aperture 94. However, once the passengerreleases the lever 90, the compressing device 100 applies a force to thelever 90 to return the latching mechanism 76 to the engaged position.

The projection 86 is positioned on a lower surface 106 of the lever 90.When the lever 90 is in the engaged position, the projection 86 extendsbelow the lower surface 44 of the amenity compartment 14. As a result,when the tray table assembly 16 is in a stowed position and the lever 90is in the engaged position, the projection 86 extends into thereceptacle 84 of the latch keeper 78 to maintain the tray table assembly16 in the stowed position. When the lever 90 is raised by a passenger tothe disengaged position, the projection 86 is removed from thereceptacle 84 and the tray table assembly 16 rotates to a deployedposition.

Other types of engagement between the tray table assembly 16 and theseat back 12 include but are not limited to the type of latch commonlyused for mounted tray tables on an aircraft, a slam latch, a pivotlatch, snaps, hook and loop fasteners, snap-fit, or any other suitablereleasable fastening device.
